The American Ninja Warrior course is not as easy as it looks. Most of us would probably have trouble getting through one obstacle.

That’s what makes Jimmy Choi‘s accomplishment so special. On Monday Choi, 41, made it through not just one but two obstacles on American Ninja Warrior despite the fact that he has Parkinson’s Disease.

Think about that for a minute. Let the awesomeness sink in.

Choi was diagnosed with young-onset Parkinson’s when he was just 27 years old. After a few years of depression that his wife calls “the dark years,” Choi made a life-changing discovery: exercise helps ease the debilitating symptoms. So despite the fact that he struggles with simple tasks like tying his shoes or buttoning his shirt, Choi started working out. Pretty soon he was running half marathons. Then triathlons. Then full-length marathons. To date he’s now completed over a dozen marathons and over 75 half marathons, raising over $100,000 for Michael J. Fox‘s charitable foundation, Team Fox.

More recently Choi started doing ninja training with his daughter. When she asked him to try to compete on American Ninja Warrior, he couldn’t say no. And that brings us to Monday.

With his family in attendance, Choi took the platform at the American Ninja Warrior Kansas City qualifiers and showed everyone suffering from Parkinson’s that the disease does not have to define them.
